长城岭隧道事故多发原因分析及处置措施

The Cause Analysis and Disposal Measures of the Frequent Accidents in the Great Wall Ridge Tunnel

针对忻阜高速长城岭隧道事故多发问题比较突出的特点,根据交通事故发生的原因进行分析,主要原因为隧道水泥路面磨损严重,路面湿滑和油污,造成隧道路面抗滑能力严重不足,标志标示及设施不完善和驾驶人的不良驾驶习惯。根据隧道事故发生的原因,针对性地采取处置措施,采用复合式路面提高路面的抗滑能力,在隧道入口处增加限速措施,降低车辆驶入隧道的速度,有效避免事故的发生,经过连续4年的不间断完善,有效地降低了长城岭隧道的事故发生率,取得了较好的成果。

According to the cause of the tunnel accident, this paper dealt with the disposal measures pointedly to improve the anti-skid ability of the pavement by adopting the composite pavements. It also reduced the speed of vehicles entering the tunnel by increasing the speed limit at the tunnel entrance, which effectively reduced the accident rate of the Great Wall Ridge Tunnel and achieved the good results.
